Metastatic tumors of the myocardium

The importance of the electrocardiographic study made with the exercise test is emphasized as the only safe means of establishing the diagnosis of latent coronary ostial stenosis. Routine use of the electrocardiographic study and exercise test in early cases with a systematic follow-up in subsequent years is urged in order to discover cardiovascular syphilis at an earlier stage than has been possible heretofore.
